摘要
以毛竹废弃物为原料,采用自制设备制备毛竹成型颗粒,分析了粉碎粒径、含水率、预热温度、成型压力对颗粒成型的影响,并以松弛密度、耐久度为指标,采用单因素及正交试验对毛竹成型颗粒制备工艺参数进行了优化。结果表明:当粒径小于0.38 mm,含水率为15%,预热温度为125℃,成型压力为20 MPa时,成型效果最好,此时成型颗粒的松弛密度为1.110 g/cm3,耐久性为0.955。该工艺的优化设计为毛竹废弃物制备成型颗粒工艺参数的选择提供了参考。
Moso bamboo was used as the raw material.The influences of the process parameters including the grain size, the moisture content, the preheating temperature, and the applied forces of the raw materials on the loose density and durability of bamboo pellets were studied by using the orthogonal experiments in this paper.The optimum factors were as follows, the grain size of raw materials was 0.38 mm, the moisture content was 15%, the preheating temperature was 125 ℃, and the pressure was 20 MPa. Under this condition, the loose density reached 1.110 g/cm3 and the durability reached 0.955.
